Comparative Amplicon and Shotgun Metagenome Profiling of Soil Microbial Communities in Kauri Forests Affected by Phytophthora agathidicida

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Soils beneath symptomatic and asymptomatic kauri trees were analysed using LAMP, amplicon sequencing, shotgun metagenomics, and PICRUSt2. LAMP detected Phytophthora agathidicida in 39/60 samples, while shotgun metagenomics detected it at low abundance across all samples.
